275 is a great overclock, I'd be happy with it. I've been running the 3500LLPRO kit at 270 for well over a year now, rock stable. Corsair pushed out some amazing DDR1 right before DDR2 hogged the limelight.

TWINX2048 / Opteron 185

I have been running the Corsair TWINX2048 for over a year at a FSB of 275 @ 1:1 timing with these settings 3-3-3-8 1T. My CPU is an Opteron 185 (275X11=3050Mhz) on a DFI LANParty UT SLI-D with eVGA 8800 GTS 640 video card. My system is stable in 3D games and benches very well but I cannot push the ram above 275. I am happy with this level of performance and will wait to see what the Quad core war looks like when AMD finally has as single CPU quad out to comapre to the Intel offerings.

You will have a nice boost. You may not notice from regular desktop use, but then again you may. Memory is sometimes hard to see a difference right away, except for benchmarks.

Run everest now, and then when you get the kit.. that's where you will see differences. The biggest difference is going from 2T to 1T timings, then the added speed is a bonus.

There is a significant difference between those two kits though. You'll love the 4400PRO. I also highly recommend the 3500LL PRO 2GB kit. Don't hestitate to pick up whatever one is cheaper. I have had better performance out of the 3500LL PRO kit, believe it or not.

hi Rob,

I am very new to overclocking and have few noob questions... If I am replacing my current Kingston DDR400 512mb x 4 with this kit, how much gain in performance can I expect? Will it be a noticeable difference? Many thx in advance

No worries about bitching, I can understand the frustration. It's too bad that more things are not using the PCI-E 1x and 4x slots :/

Got the A8N32SLI

The memory does not seem to have an issue with this board and I have options out the ying yang. It's annoying that the 7900GTX SLI setup blocks all but one pci slot. I had to go with the hauppage tv tuner over the Xfi. Tough choice, I don't want to spend any more money for crap I already have (ie usb tuner). Hey, thanks for all your help, sorry for bitching.

I am not sure if it's a directly similar board, but Corsair tested 20 of these kits in an A8N-SLI Premium and each and every one worked fine. They were also using an X2 4200+, which makes this even more odd.

You may want to read Redbeards last post in this thread regarding the memory. It could be a BIOS issue, I am not positive. He ran his X2 4200+ at 2.75GHz though.

Those two boards,(the deluxe vs premium) do have some differences outside the NB heatpipe. I'm tempted to try one, and would prefer the premium over the newer a8n32 so when SLI is used with dual slot cards, I still have two pci slots available. Thanks for your help and resourcefulness.

I would throw your Vcore at 1.45 and your memory voltage at 2.8v. I can't see why 3-4-4-8 at 1T would not be possible at these settings, or a CPU overclock for that matter.

I tried. Same thing. If I were to experiment, does a newer mobo make sense? The DFI from you article sounds like a later model than the a8n sli deluxe. Perhaps it's more capable. Either way, the ram still runs at rated speed, I do miss 1t capability. Once you go blinking lights on your memory, you can't turn back......

The multiplier is 4 for HTT. So, as far as i can tell, a 250mhz fsb times 4 should be right in spec (with the exception of a 250mhz fsb...). It would normally be 5x200, so not sure if the NB is an issue or not since the resulting frequencys are the same. Maybe SLI adds a strain to these conditions. I'll play around some. I did try 1t and using extreamly loose timings otherwise, same result. I guess timings can be tricky from mobo to mobo.

There's definitely something there messing with you. I blame it on Infineon

Dunno if it's the mobo or the cpu. I've upgraded my PSU(mostly for the SLI configuration), and my overclocking experiences remain consistent, and the new ram experiences reflect similar cpu core results. But never before was I able to run such frequencys with the cpu/mem at 1:1.
The mobo won't allow for higher core voltage than 1.45, and no NB adjustment. the NB still runs at 1000 HTT, dunno if 4*250 settings require higher voltage for that. Think it may be the motherboard or the infineon chips?
